Paul saw the misinformed conscience of the unbeliever or “weak” person here as a real shortcoming. And he emphasized the responsibility of the strong (Those strong in the Lord) to be patient with the weak. Thus, this left no room for petty egos, prideful boasts, or haughty behavior to rule over & possibly ruin the relationships. But neither is Paul saying that we need to modify the Gospel Message just in order to please people. (Galatians 1:10) Using Jesus as an example, Paul quotes Psalm 69:9, where Christ’s willingness to deny Himself & suffer for the benefit of others should be our goal…for it’s in love, humility, & edification that we can reach the lost.
